How I got my car registered and insured in MA (step-by-step, sorta)

Funny you mention the dryer sheets - I’ve heard that trick from a bunch of folks, but I’m never totally convinced they do much. Still, I toss a couple in the trunk and under the seats every fall, just in case. My dad swears by Irish Spring soap bars, cut up and scattered around the garage. He claims the smell keeps everything from mice to raccoons away, but honestly, I think it just makes his garage smell like a locker room.

Had a similar run-in with mice a few years back, but in our old Sienna minivan. Left it parked for a couple months while we were between moves, and when I finally opened the glove box, there was a whole nest made out of napkins and receipts. They chewed through a pack of gum but left the registration papers untouched. Go figure. Ever since then, I try to keep food out of the car entirely, but with kids, that’s basically impossible.

One thing I did notice - leather and anything with a strong scent (like those old pouches or even some car fresheners) seem to get left alone more often than not. Maybe there’s something to it, or maybe mice just have weird taste.

Anyway, I’d rather deal with paperwork at the RMV than another mouse nest in the air filter. At least the RMV doesn’t chew through your wires...

I get where you’re coming from with the dryer sheets and Irish Spring. My uncle does the same soap thing in his shed, and honestly, I’m not sure if it works or if it just covers up the smell of whatever else is living in there. But hey, if it gives some peace of mind, why not? I’m a little skeptical about all those “life hacks” for mice, but at this point I’ll try anything short of setting up a tent in my car overnight.

The food thing is a real struggle, especially if you’re hauling kids around. I swear, no matter how many times I clean out the backseat, there’s always a rogue cracker or half-melted fruit snack wedged somewhere. I’ve heard that even just crumbs can attract them, which is kind of terrifying when you think about how impossible it is to keep a car totally crumb-free.

Funny about the gum vs. registration papers - maybe mice are picky eaters after all? Or maybe they’re just as confused by DMV paperwork as the rest of us. I had a mouse chew through a pair of earbuds once but left an old granola bar untouched. Makes you wonder what’s actually in those things.

I’d take a stack of RMV forms over mouse damage any day too. At least paperwork doesn’t leave droppings behind... unless you count the mess of forms they give you. Anyway, props for sticking with it and getting through all the MA registration stuff. That process is enough to make anyone want to hide in their trunk with a bar of soap.

I had a mouse chew through a pair of earbuds once but left an old granola bar untouched. Makes you wonder what’s actually in those things.

That cracked me up. I had one gnaw up the seatbelt in my old Corolla, but left a bag of stale chips right next to it. Maybe they’re just out for revenge on anything useful. And yeah, “life hacks” for mice always seem hit or miss - my neighbor swears by peppermint oil, but all it did was make the car smell like toothpaste for a week. At least the RMV doesn’t require proof your car is rodent-free... yet.

I’ve tried the peppermint oil thing too - total waste of time for me. The mice just seemed to ignore it and kept doing their thing. I even tried those ultrasonic plug-in things in my garage, but honestly, I think the only thing they scared off was my dog. Has anyone actually found something that works, or are we all just stuck with mouse-proofing our cars with wishful thinking?

I hear you on the peppermint oil and those ultrasonic gadgets - they really don’t seem to do much for most folks. In my experience, the only thing that’s made a real difference is physically blocking off entry points. Some people use steel wool or metal mesh in vents and around wiring, which seems to actually keep them out. It’s not a perfect solution, but it’s a lot more effective than sprays or plug-ins. Also, keeping food or snacks out of the car helps more than you’d think... mice love a reason to stick around.

Steel wool is my go-to too, but have you ever tried getting it into those weird little gaps behind the pedals? I swear, whoever designs car interiors must have a grudge against people with big hands. I’ve also heard someone say Irish Spring soap works, but honestly, that just made my car smell like a grandma’s bathroom and the mice didn’t care. Anyone actually had luck with that? Or is it just another internet myth...

I’ve tried the Irish Spring trick and honestly, same result - just a weird, overpowering scent and the mice didn’t seem bothered at all. I think it’s one of those things that sounds clever but doesn’t really hold up in practice. Steel wool is definitely more effective, but yeah, those tight spots behind the pedals are a pain. I’m always a little nervous about stuffing anything down there, though. If a bit of steel wool comes loose, it could get wedged under a pedal and cause a safety issue.

One thing I’ve done is cut the steel wool into smaller pieces and use a pair of long tweezers or needle-nose pliers to wedge it in place. It takes some patience, but at least I know it’s secure and not going to shift around while I’m driving. I’d avoid using anything that could break apart or leave residue near the pedals - just not worth the risk.

If you’re worried about mice, it might be better to focus on sealing up any entry points under the hood or around the cabin instead of relying on scents or deterrents inside the car. Traps outside the vehicle can help too. I get wanting a quick fix, but anything that could interfere with driving just isn’t worth it for me.

I get what you mean about being nervous with steel wool near the pedals. That’s always been my worry too - especially since I drive a car where replacing anything under the dash costs a fortune. I tried the Irish Spring thing once and honestly, it just made my car smell like a mix between a soap factory and a mouse nest. Didn’t seem to slow the mice down at all.

This is really the key, I think. I had a similar issue last winter, and after a lot of frustration, I ended up crawling under the car with a flashlight and some cheap silicone caulk. Sealed up a couple of gaps where wiring comes through. Haven’t had a problem since. It wasn’t glamorous, but it was way cheaper than dealing with chewed wires or cleaning out nests.

Do you know if there are any specific spots in newer cars that are more vulnerable? I’ve heard some luxury brands use soy-based wiring insulation now, which is basically a buffet for rodents. Makes me wonder if there’s a better long-term fix than just plugging holes and hoping for the best...

- That soy-based wiring is a real pain - my buddy’s 2018 Lexus had a nest right on top of the fuse box last year.

“Sealed up a couple of gaps where wiring comes through. Haven’t had a problem since.”

I keep hearing about rodents loving that soy wiring, but is it really that much worse than the old stuff? I mean, my dad’s ‘99 Camry had a mouse problem too, and that was way before the “eco” plastics. Stainless mesh sounds smart though - does it actually stay put with all the engine heat and vibration?

Honestly, I’ve wondered the same thing about the soy wiring hype. My neighbor’s got a 2018 Lexus and swears the squirrels treat it like a salad bar, but my old E-Class had its share of chewed wires long before “eco” anything was a thing. Maybe rodents just have expensive taste?

As for the stainless mesh, I tried it after a chipmunk decided my engine bay was prime real estate. It actually held up better than I expected - didn’t rattle loose, even after a few months of Boston potholes and heat waves. Just make sure to zip-tie it down tight. Still, nothing’s totally rodent-proof... I caught one little guy nesting inside my air filter box last winter. If only they’d pay rent, right?

If only they’d pay rent, right?

You’re not kidding about the rent - at this point, I’d settle for them just not chewing through my vacuum lines. I’ve always thought the soy wiring thing was a bit overblown too. My ‘92 Volvo had wires gnawed on long before “eco” was a buzzword. Stainless mesh is a solid move, though. I’ve used hardware cloth and zip ties myself - cheap, effective, and you don’t have to shell out for those fancy sprays. Nothing’s perfect, but it beats paying for a new harness every spring.

Funny you mention the hardware cloth - I did almost the same thing after finding a mouse nest in my air filter. Just wrapped some around the main wiring runs and used those big zip ties. It’s not pretty, but it’s held up for two winters now. I tried peppermint oil too, but honestly, I think the mice just got used to it after a while. The mesh seems like the only thing that actually works long-term.

Yeah, the peppermint oil thing is kind of a joke at this point - my dad swears by it, but I think the mice just treat it like air freshener. I had a similar mouse issue last fall, except they chewed up some insulation under the hood. Ended up using hardware cloth too, and it’s ugly, but honestly, who cares if it works? I’d rather have a ratty-looking engine bay than surprise rodent damage.

I’m convinced the mice in my garage are running a spa with all the peppermint oil I’ve tried. I even caught one sitting on my S-Class’s intake manifold looking way too relaxed for my liking. Maybe they’re just connoisseurs of luxury scents now?

But yeah, I totally get what you mean about hardware cloth. I had to wrap some around the wiring harness under the hood after finding a nest (with acorns, no less) wedged behind the battery. It looks like something out of a Mad Max movie under there now. I used to care about keeping everything pristine, but after that repair bill? Nope. Function over form every time.

Curious though - has anyone actually found a solution that doesn’t make your engine bay look like a DIY fortress? Or is this just the price we pay for living in New England with nice cars and creative rodents? I’ve heard about those ultrasonic repellers, but honestly, do they work or is it just another “air freshener” for the mice?

And while we’re talking about ugly fixes, does anyone else feel weird explaining to the service guys why there’s chicken wire zip-tied everywhere? Last time I went in for an oil change, the tech just nodded and said, “Mice?” like it was totally normal. Guess it kind of is around here.

Anyway, if anyone’s figured out how to keep things both mouse-free and not embarrassing at Cars & Coffee, I’m all ears. Otherwise, I’ll just keep telling myself that “rat rod” look is coming back in style...

- Totally get where you’re coming from - rodent damage claims are way more common than people think, especially around here.
- Hardware cloth and zip ties might not win any beauty contests, but honestly, it’s better than another four-figure repair bill.
- Ultrasonic repellers? Mixed results. Some folks swear by them, others say the mice just ignore the noise and keep nesting.
- Service techs have seen it all. You’re definitely not alone with the chicken wire setup - most just nod and move on.
- At the end of the day, protecting your car is what matters. If anyone gives you grief at Cars & Coffee, just tell them it’s “custom anti-theft.”

I get the appeal of hardware cloth and zip ties - cheap, effective, and you can do it yourself. But has anyone considered the long-term downsides? I’ve heard stories where moisture gets trapped under the mesh and causes rust, especially in our salty winters. Also, with insurance, do they ever give pushback if you’ve modified the undercarriage like that? I’m not saying don’t do it, just wondering if anyone’s run into issues down the line. For me, I’m still on the fence about ultrasonic repellents...I mean, if they work even 50% of the time, isn’t that worth a shot before drilling or zip-tying stuff under the hood?

Also, with insurance, do they ever give pushback if you’ve modified the undercarriage like that?

Honestly, it depends on the company, but most of the time, unless you’re welding a flamethrower under there, they probably won’t care about a bit of mesh and zip ties. That said, if rust turns into a structural issue and you try to claim it, you might get some side-eye. I’ve seen some wild DIY stuff over the years - one guy tried to claim damage from “homemade rodent armor” that basically turned into a rust farm. Ultrasonic repellents? If they work half the time, that’s still less hassle than arguing with an adjuster about why your car looks like a squirrel-proof bird feeder...

I’ve actually had to look at a claim where someone zip-tied chicken wire under their car to keep out chipmunks. It worked… until it didn’t, and then the rust was wild. Insurance folks get suspicious when DIY stuff causes more problems than it solves. Mesh is fine, but if it starts looking like a science project gone wrong, expect questions.

Mesh is fine, but if it starts looking like a science project gone wrong, expect questions.

That’s honestly kind of wild. I get why someone would try the chicken wire thing - chipmunks can do real damage - but I’ve always wondered about long-term effects. Did they actually attach it right to the undercarriage? I’d be worried about trapping moisture and road salt, especially with all the snow we get around here. Seems like rust is almost guaranteed.

I’m curious if anyone’s ever had luck with the “official” rodent deterrent tapes or sprays instead. Or maybe those electronic noise things? I feel like insurance companies look for any excuse to deny a claim, especially when DIY stuff backfires. But then again, leaving your car open to critter damage isn’t much better.

Is there any method that doesn’t end up costing you more down the line? Every time I try to be proactive, it feels like I’m just creating new problems...
